Project aim
-----------

[](#project-aim)

This library aims at providing abstraction for a basic changeset computer.

The idea was born from all the code duplication in the `UnitOfWork` components of the various [doctrine projects](https://github.com/doctrine), which all require complex calculations of changes in sets of objects over time.

With this repository, I aim at creating a simple maximum common denominator between those [`UnitOfWork`](http://martinfowler.com/eaaCatalog/unitOfWork.html) implementations by extracting common API and re-implementing it in a cleaner and hopefully more efficient way.

The project is a **work in progress**, so don't expect it to be usable until version `1.0.0` is tagged.
